East Japan Railway Company

May 11, 2010

The new high–speed Shinkansen train (E5 Series) begins commercial operation in March 2011 between Tokyo and Shin–Aomori on the Tohoku Shinkansen line.

East Japan Railway Company (JR East) announced in April 2008 that it would be introducing a first class "Super Green Car" (provisional name), a first for any Shinkansen in Japan, on the E5 trains that are to begin service. The official name, interior design and other details of the first class car have now been decided.

The first class car will offer a high–class and roomy transportation space and service unprecedented in the railroad world.



Official name


Derivation of name

    The name combines "gran" (French for "grand") with the English word "class." Roominess and comfort, in addition to luxury, are major characteristics of the car. The name "Gran Clase" is used for some of Europe’s high–end rail cars.
